SUCKER-ROD ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 442,942, dated December 16, 1890*.

Application tiled September 17, 1890. Serial No. 365,221. (No model.)

To all whom t may concern:

Be it known thatl, HIRAM BICKEL, of Guiey, in the county of McKean and State of Pennsylvania, have invented certain new and useful Improvements in Sucker-Rod Elevators; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in sucker-rod elevators; and it consists in the combination and construction of parts, which will he fully described hereinafter.

The object ot my invention is to provide'a suitable means for taking hold of and locking the square neck of the sucker-rod into an angular jaw or block, so as to lower the rods into or pull them out of a well, and for screwing and unscrewing the rods, and to enable the jaw or block to he quickly and readily separated from the rod.

Figurel is a plan view of a device embodying my invention,the block and the leverbeing shown in a line with each other and the block shown in section. Fig. 2 is a side elevation of thel same, showing the two parts at an angle to each other. Fig. 3 is a detail view showing the beveled sides on the lever or handle.

A represents the handle or lever, which will be of any desired length, and which is made bifurcated at its inner end, so as to allow the jaw or block B to be pivoted between the ends and partiallyrevolve between them. Each of the prongs C of the rod or lever is provided with a shoulder or stop D to limit the distance that the block shall turn. In the inner end of the recess in the lever there is formed the stop or shoulder G, which serves to limit the movement of the jaw or block when the two parts'are turned into a line with each other, and the sides of the recess below this shoulder G are beveled away, as shown at II, so that when the block or jaw is closed these beveled sides will cause the spring-catches to open for the purpose of releasing the rod. .Iournaled between the two prongs of theleveris the angular jaw or block B, which is adapted to turn through oneline with the lever or handle, as shown in Fig. l, when the jaw or block is applied to or removed frein the neck of a sucker-rod, and to stand at a right angle thereto when the lever is to be used in lowering a sucker-rod into a well or removing it therefrom. In order to limit the turning movement of the block or jaw as the two parts are to be turned at right angles to each other, as shown in Fig. 2, the block is provided with two stops I, which catch against the shoulders D upon the prongs of the handle or lever, and thus prevent the block from turning beyond a certain point. ln one end of the block or jaw is made a suitable recess, in which the neck of the sucker-rod is made to catch, and which rod is held as nearly as possible in a line with the handle or lever, so that only a direct pull will be exerted thereon. Pivot-ed in this block are the two catches J, which have their front ends to project into the recess in the end of the jaw or block to receive the neck of the sucker-rod, and which have their outer ends to project through the opening made in the block, so that these outer ends will project sufficiently far beyond the sides ot' the extended portion L of the block to be operated by the inclined sides ll of the handle or lever when the jaw or block is turned into a line with it. The moment the lever is moved so that the extended end L of the block does not catch in the recess inthe handle or lever these spring-catches snap outward at their outer ends and inward at theirinner ones, so as to close the slot and thus prevent the rod from becoming detached from the jaw or block. The catches are also adapted to be operated by hand when the elevator is to be removed from the rod. While the block or jaw and the handle orlever are in a line with each other, as shown in Fig. l, the catches are open, so that the jaw can be freely applied to or removed from the neck of a suckerrod; but when the two parts are turned at an angle, as shown at Fig. 2, the catches are closed,so that the sucker-rod cannot possibly become detached while it is being lowered into or raised from the well.

Having thus described my invention, I claiml. The combination of the handle provided quarter of a circle, so as to stand either in a IOC) with u pronged end and inclined edges upon the inner sides of the prongs at or near their inner ends, ai block pivoted between the outer ends of theprongs, hzwingan opening for the sucker-rod, and spring-actuated catches pivoted upon the block, theirouter ends adapted to1etain the rod and their inner ends to engage the inclined edges when the block and handle are in L line, combined to operate in the manner described.

2. The combination of the handle or lever provided with zi pronged end and :i stop or shoulder G, with the block. or jaw provided with a recess to receive the neck of the sucker-rod and with the studs or projections to limit; its turning movement, and the automatically-acting catches pivoted in the block7 and which are operated by the sides of the recess in the end of the handle or lever, substantially as described.

In testimony whereof I atlix my signature in presence of two witnesses..
